The Bykski A-SP7900XTX-X is a full-coverage GPU water block engineered for Sapphire Radeon RX 7900 series graphics cards. The nickel-plated T2 copper cold plate covers the GPU chip, while thermal pads transfer heat from the onboard memory and power stages into the cooling loop.

Replacing the stock air cooler with liquid cooling lowers sustained temperatures under heavy board power and eliminates fan noise from the system. A clear acrylic top displays coolant flow across the 0.3 mm micro-channels, and an aluminum backplate braces the circuit board.

Warnings

Warranty is repair or replacement. All returns are accepted within 30 days, no questions asked. An installed or used item comes back at a higher restocking fee.

The top is acrylic. Tighten mounting screws evenly and finger tight - over-tightening cracks acrylic, and a cracked top is not covered. Installation removes the card's stock cooler, so never power the card without the loop installed and the pump running. Thermal pads go where the block has corresponding raised contact points; the die itself uses thermal paste.
